<p>I had decimal values such as <code>0.01235</code> and <code>0.016858542</code> that I wanted to convert to percentages 1.235% and 1.6858542% respectively. I thought it was going to be easy, just calculate <code>(0.012858542 * 100)</code> and I'm good to go. I was wrong, <code>(0.012858542 * 100) = 1.2858542000000002</code> because of decimal conversion.</p>

<p>Let's add <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toFixed" rel="nofollow noreferrer"><code>toFixed()</code></a> to the calculation and I end up with the right value.</p>

<pre><code>(0.012858542*100).toFixed(7)    // returns "1.2858542"
(0.01235*100).toFixed(7)        // returns "1.2350000"
</code></pre>

<p>I don't like to show four trailing zeros when they're unnecessary. One solution I thought about was to use <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace" rel="nofollow noreferrer"><code>replace()</code></a> to remove all trailing zeros but I ended up using <a href="http://numeraljs.com/" rel="nofollow noreferrer">Numeral.js</a> instead because it does all the work for me while it's lightweight. I can recommend it!</p>

<pre><code>import numeral from 'numeral';

numeral(0.012858542 * 100).format('0.00[0000]') // returns "1.2858542"
numeral(0.01235 * 100).format('0.00[0000]')     // returns "1.235"

<p>Was using ExtJS for formatting numbers to percentage earlier. Now as we are not using ExtJS anymore same has to be accomplished using normal JavaScript.</p>

<p>Need a method that will take number and format (usually in %) and convert that number to that format. </p>

<pre><code>0 -&gt; 0.00% = 0.00%
25 -&gt; 0.00% = 25.00%
50 -&gt; 0.00% = 50.00%
150 -&gt; 0.00% = 150.00%

 之前使用ExtJS将数字格式化为百分比。现在，由于我们不再使用ExtJS，因此必须使用普通的JavaScript来完成同样的操作。 需要一个方法，将采取数字和格式(通常在%)，并将该数字转换为该格式。 0 -> 0.00% = 0.00%25 -> 0.00% = 25.00%50 -> 0.00% = 50.00%150 -> 0.00% = 150.00%
